Greek classes / activities / childminder for 18m.o

[Alf_Theo]

I am trying to speak as much Greek to my little boy Rafael (born June 2017) but am keen for him to have more exposure to the language (preferably more accurate that my Greek too!) - grateful for any suggestions around classes or activities with as much Greek speaking as possible aimed at pre-schoolers or indeed if anyone knows a childminder or has there own kids that they just want to get used to hearing the Greek language. Relatively new to the area so thought I'd try on here :-)

Many thanks in advance

Alf
